MISSION

Mack’s mission is Total Customer Satisfaction. Though simple in wording, this principle drives every major decision the company makes. For example, entering the rapid prototyping and tooling markets was a direct response to customer feedback and the need to accelerate time-to-market. Likewise, expanding the headquarters facility to increase contract manufacturing capacity was driven by growing market demand.

But beyond responding to customers’ needs to further grow the business, Mack also formally measures customer satisfaction on a quarterly basis around four criteria:

  • Return rate
  • Number of on-time deliveries
  • How the customer ranks Mack as a supplier in relation to its competitors
  • General feedback from customers

Results are posted in all plants and compensation is directly linked to customer satisfaction and profitability.
